To aZZfw/w//az't may concer-n.'

Be vit` known that 1,' JOSEPH BOUCHARD, a subject of the King `of Great Britain, residing at Lachine,` Province `of Quebec, Canada, have invented certain new and useful Improvements in Plows; and I do' hereby. declare that the following fis a full, clear, and exact description ot' the invention, such as will enable others skilledfin the art to which it ajfip'ertains to make and use the same.` y y y The present invention vpertains to a' plow and particularly one designed for work upon roads and'tracks of variouswidths. The plow which is a blade or scraper extending in a straight line across the track is adapted tor rotation with respect to the frame of the machine7 whereby the width ofl the space actually cleared may be regulated. j

The invention is fully disclosed in the following description and in the accompanying orawings in which:

.Figure 1 is aplan view of the device; j Figure 2 is asection on the line 2 2 of ligure 1;.

Figure 3 is a similar view showing the scraper in inoperative position;

Figure 4 is a section on the line 1 4 of Figure 2; j f

Figure 5 is a detail view of the adjusting mechanism;` f

Figure 6 is a perspective View ofthe shoe;

Figure 7 is a'fragmentary section partly` in elevationy ofthe upper end of one of the posts on the line '7 '7 of Figure 1;

Figure 8 isa section on the line 8 8 of Figure 2; j

Figure 9 is a front elevation ofthe guard trame applied, to the scraper; and,

Figure 1() isa section on the line 10 1O of Figure 2.

As shown in Figure 1, the frame of the device includes a pair o'f side or body members 1 through each of which is passed a vertical post or bolt 2. To the lower end of each post is fixed a sleeve 3 in which a ground wheel d is journalled. The forward ends oit the side members are concaved, as indicated by the numeral 5 in Figure 2, and have secured thereto a snow scraper or blade 6 by means of fastening devices 7. An arm 8 is pivoted to the upper surface of the blade intermediate its ends and carries a scat 9 disposed between the side members 1. At the same point on the blade is pivoted a bar 10 which telescopically receives a draft tongue 11 to't-he free end of which is attached the usual harness orthe like (not shown).- On'the top of the blafde is also mounted a semi-circular adjustment member 121'the central portion of which rests on the bar 105 as shown in Figuresy 1 and 2. This member is constructed of' angle'ironand has its "ends curved downwardly to engage the back of the scraper 6 and are riveted thereto, as indicatedby the immerallt Iin F igurell. The vertical side o1 the angular member is notched as at 15 for the reception o1 alocking leve-r 16 which is pivoted on the top of the bar 10. This lever is operable from a. foot` pedal 17 within the reach of the operator when heis positioned on the seat 9. forward end otgthe lever is connected'to the bar by means of a spring 18 by means of which it is heldin registration with one of the vnotches 15. On the top of the bar 10 at opposite sides or' the member 12 are mounted guide members 19 and 2O for keeping the lever in proper alignment'. j

When thefscraper is in the position shown in Figure 1, the machine will clear the maximum width. In the event that' the koperator desires that ak smaller'` width beV cleared, he causes the entire machine to be.

turned so as to give the ydesired angularity to the scraper with respect to the road, upon which; the width of the area `directly beneath the scraper depends.' The operator then releases `the lever 16 from the adjustment member and causes the bar 10 to be'tur'ned again in alignment with theroad. Hek then releases the ypedal 17 to allow the locking lever again to drop into the notch over which it is now positionedy V rThe side members l heilig secured 'to the scraper as shown'in Figure 1Q will carry the wheels 4 to planes perpendicular to that of. the blade. It is therefore necessary that the wheels be turned back into parallelism withk the bar 10, and for this purpose there is disposed in each side men'iber adjacent the post 2 a disc 21 eccentrically mounted on a shaft 22 equipped at its upper end with a handle 23. The sides. ot each body member are slotted as at 211 and in these slots is litted a fork 25 which straddles the disc and which is keyed to the post by means of a lug 26 received in a groove 27 formed longitudinally of the post. Upon rotation oit' the shaft 22` the fork is moved in one direction or the other carrying with it the post 2 and. wheel. 4t.

The

,standing flugs .36 `.are ,formed on the .body

On .the ishaft is :fixed .a pair .of `handles. 40 Twithin .the .reach of r the drivers :seat .and normally pointing forwardly. .An upward .pull .on the Ahandles .tends to .pull the lin-ks. .3S .and levers. 3.4 downwardly, but fsuch movement .is not possible because `of Ithe arms lbeing joined-to thenppeimends-of ythe iposts .2 `Whicli.are immovable vertically. `l\lo i'eove1'the forward end 1,1.,of Vthe nnachine is .also -,similar ly immovable, .being secured ,to .the .draft animals, :thescraper '6 andside members lbeingthe only vertically movable parts. Since .the lever .341. .cannot follow its tendencv to .move downwardly,

1 continued lnull on .the Ahandles 40 .causes -the side .members f. and the .blade to rise to the position shownin Figure 3. Thus, the blade or scraper is .raised from .the ground .together with thesidemembersand the latter can be locked ,in .adjusted positions .in

The .locking device comprises abell-crank lever 42 y(Fig. 8) pivoted 'between .ears 43 formed `on -each side nnember, one lend :of

-On'thenpper--edge--of-the blade is secured a pair of bearing members 50 in which are The latter serve to support a frame 52 disposed in ad- Vance of the'blade for spreading stones or the like on the road. `At `varionspoi-nts on the `frame are.providedstnds v.5.3 engaging the blade ,andholdingthe*frame in spaced relation therefrom.
